Letters Patent No. 104,050, dated June 7, 1870.

IMPROVEMENT IN FAUCETS.

The Schedule referred to in these Letters Patent and' making part of the same.

To all persons to whom these presents may come:

Be-it known that I, WILLIAM MGKAY, of New; buryport, of the county of Essex and State of Massachusetts, have made a new and useful invention or improvement having reference to Taps and Faucets for Beer or other Barrels; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, of which- Figurel is a longitudinal section, and

Figure 2 is an external elevation of a tap and faucet embodying my invention.

Figure 3 is aside view of the tubular key of the tap.

' In this'cuse the tap becomes an auxiliary faucet, to be opened by the primary faucet during the act of screwing it into the tap, the said tap being, also, closed by and during the act of separating the primary faucet from it.

The said primary faucet, shown at A in the drawing, is like a common stop-cock, except that one ofI its connection-screws, a b, (viz, that marked (1,) is fin-med'with a prismatic bore,'c, to receive and tit upon the prismatic head d of the rotary key B of the auxiliary faucet or tap, as it may be termed.

rIhe screw a is to have its thread pitched in a direction opposite to that of the male screw e of the key B. In other words, the screw a is to be a,right and the screw e a left screw.

The body j' of the key B is cylindrical, and is provided with a flange, g, extended from it and the prismatic head d. It also has a male screw, e, projected from it, the whole being formed and arranged as represented. A

Furthermore, a passage, h., is bored or made axially into the key B from its outer end, and has one or more passages, t', leading laterally out of it, near its inner end.

The plug C, or body of the auxiliary faucet or tap, is constructed with a cylindrical chamber, It, (see Figure 4,) which is a lo'iigitudinal section of theplug as it appears when separated from its key. l

From the rear end of the chamber a female screw, l, is cut through the plugV tov receive the screw e of the key.

l `urthermore, vat the front end of the said chamber,

is a shoulder, m, for the iiange g to bring up against.VA

The body C also has another female screw, s, made in it, toreceive the screw a ofthe main faucet.

The diameter ofthe plug-chamber k corresponds to the diameter of the part or body f of the key, and there is lcd laterally out of the chamber lo by one or more holes, n, which go through the -plug C.

The plug is made slightly tapering, so that it may be driven into and caused to' closely iit to a hole when made to receive it in the head of a' barrel.

The screw b of the main faucet is provided with a thimble, o, which screws upon it. and has a pipe or passages n should project into the barrel a short distance beyond such head.

While the tubular key B may be screwed onto the plug far enough to carry the lateral passages t' beyond the lateral passages a, no liquid can iiow from the barrel through the` passages n and into and through Oonse-' the passages i, and thence into the bore h. quently, the barrel will be closed by the auxiliary faucet o1' tap. But, on screwing the, main or primary faucet into the tapfthe key B will be revolved, its screw c in the meantime causing the key to more endwise until the holes 'i may be carried opposite the holes n, which will have taken place when the primary faucet ymay have been.v fully screwed into the plug, so as to carry the shoulder q of the screw a up to the end ofthe plug.

As soon as the lateral passages of the -key and body of the plug may be brought into conjunction,

liquid from the cask or barrel will flow into the bore 7i., and thence into the primary faucet, from which it may be discharged by properly turning the key fr thereof, so as to allow the liquid to low through it.

I am aware of the invention described in the United States patent No. 62,864, the purpose of which is to force, by means of a faucet,.a plug out of its hole ina barrel. I make no claim to such invention, as,

although in some respects it is analogous to my apparatus, as described, yet in others it differs materially the body C, as having the cylindrical chamber It, the

opposite female screws ls, and one or more lateral passages, u, all the parts being constructed and ar ranged substantially as described.

Also, the combination of the above with the main` faucet, as constructed, with the key-receiving socket;

c and the male screw a, arranged with such socket, and for the coupling with the screw s ofthe tap C, as

set forth.

WILLIAMMCKAY.
